anonymous · Answer

$$12x ^{2^{}} + 5x - 1 - (10x ^{2^{}} - 2x - 4)$$
Since there is a negative sign, you should multiply it with the variables in the parenthesis.
So we get
$$12x ^{2^{}} + 5x - 1 - 10x ^{2^{}} + 2x + 4$$

From there, you can get the answer, just subtract like terms like you would whole numbers
